6.26.12 Abnormal speed detection
H : Abnormal speed detection time
H : Overspeed detection frequency upper band
H : Overspeed detection frequency lower band
• Function
When use at speed control mode with sensor (
RV
=
), it always monitors the rotational speed of the
motor, even when the motor is at rest, and if the speed remains out of the specified limits for the specified
length of time, it outputs an error signal.
When use at speed control mode without sensor (
RV
), it always monitors the estimated rotational
speed of the motor.

6.26.14 Undervoltage trip
H : Undervoltage detection level
H : Undervoltage trip selection
• Function
This parameter is used for selecting the control mode when an undervoltage is detected. (Invalid, while the
inverter stops.)
H=: (Disabled) ················ Inverter stops,but does not trip. (FL is not active.)
H=: (Enabled) ················ Inverter stops and is tripped because an undervoltage is detected. (FL is active.)
Title Function Adjustment range Default setting
H Undervoltage detection level ~ %, %: (auto mode)
H Undervoltage trip selection : Disabled, : Enabled
Note: For H, 100% corresponds to a voltage of 200V (for 200V class) or 400V (for 400V class)
